The last time I had to install Arch was a year or so ago. Grub always gives me the most trouble but I prefer it over syslinux.


I get the GRUB rescue menu.

I have narrowed it down to two possibilities:

1.) Not recognizing the correct encrypted volume:

GRUB_CMDLINE_LINUX= cryptdevice=/dev/sdaX:label root=/dev/mapper/vg-root

The last time, I guessed at it and got it to work but I actually want to know if this is correct. I read the Arch wiki and I get so criss-cross-referenced that I am unsure.

2.) Grub installed to the wrong folder in /boot

This was something that happened previously and I just made several copies of the .img to several folders inside /boot






And just to clarify, the /etc/mkinitcpio.conf looks like this:

HOOKS="base udev autodetect keymap keyboard encrypt lvm2 block filesystems fsck"

First of all,

Some of this may be inappropriate if you have a different setup than me

And second it should be: GRUB_CMDLINE_LINUX=cryptdevice=/dev/sdx:vg-name (without the space, with a vg name and the root= should not be necessary).

Regarding grub being in the wrong folder; if you run these commands after fixing the typo in /etc/default/grub it should not matter if you have .img files elsewhere:

grub-install --recheck --target=i386-pc /dev/sdx grub-mkconfig -o /boot/grub/grub.cfg

where /dev/sdx is the hard drive where GRUB is/should be.
